Nose geometry allows for deep, straight penetration while creating a permanent wound cavity diameter exceeding that of most expanding bullets.Additionally, the bullet is solid copper, able to overcome barriers to penetration, is environmentally friendly, and does massive tissue damage on impact.Penetrating barriers such as drywall or heavy clothing prior to impacting the intended target doesn't have the potentially negative effect on the xtreme defense that it does on conventional hollow point bullets.The fluid transfers radial flutes force the hydraulic energy inward and then as the energy is restricted, it accelerates outward creating high-pressure spikes severely damaging surrounding tissue.Caliber: 45 ACPBullet Type: Lehigh Defense XD FMTBullet Weight: 135 grMuzzle Energy: 468 ft lbsMuzzle Velocity: 1250 fpsRounds Per Box: 20Boxes Per Case: 10Application: Home DefenseCasing Material: BrassHazair: YesAmmunition cannot be shipped to a P.O.
